Abstract: 1506967 Extrusion sheathing of optical fibres INTERNATIONAL STANDARD ELECTRIC CORP 20 Jan 1976 [29 Jan 1975] 02140/76 Heading B5A [Also in Division G2] A cable comprising a convoluted optical fibre 18 (e.g. of glass or silica) loosely contained in a flexible tubing 16 (e.g. of polyimide, polyamide, fluorocarbon, polyethylene, polypropylene, thermo-plastic or cross-linked polyester) is made by (a) extruding a given length of tubing 16 at a temperature above the crystalline melt point of the material; (b) feeding a smaller diameter, longer length optical fibre 18 to fit loosely within the tube; (c) longitudinally stretching the tube 16 to provide an axial strained orientation to the material (in Fig. 2, this is done by pulling capstan 24 while the tube and fibre pass through heater 20 and sizing die 22); (d) shrinking the tube 16 on to the fibre 18 to reduce the tube length and contract the fibre (in Fig. 3 this is done by driving capstan 36 slower than capstan 34 while the tub and fibre pass through heater 32) and (e) cooling the tube (e.g. at 37) to retain a given elastic orientation while permitting movement of the fibre within the tube. In a variation (Fig. 4) extruder 38 provides an oversized tube and the hot extruded tubing is then longitudinally stretched as it is drawn by the capstan 24 through the cooling chamber 40. This provides an axially oriented strain locked into the material without the added heating step of Fig. 2. A sizing die may be included in the cooling chamber 40. The tube is reheated, relaxed and shrunk as in Fig. 3.

[Also in Division E2] A magnetic core 3 (Fig. 1) for transformers or chokes comprises a stack of laminations which are held together by a non-metallic tying strip 1. The ends 1c, 1d of the strip which consists of parallel glass fibres embedded in polyester resin are overlapped and secured either by cementing or by welding. The glass fibres need not be regularly spaced in the strip (Fig. 4, not shown) and to avoid the strip being damaged by sharp edges of the laminations a hardboard sheet 2 or a number of wooden rods (Fig. 2, not shown) is provided between the laminations and the strip. The tying strip can be tightened around the laminations by applying tensioning forces to portions 4, 5 (Fig. 5, not shown) of a loop of the strip, then folding the loop over to form three adjacent layers which are welded or cemented together. Suitable tensioning forces may also be obtained before the ends of the tying strip are secured by means of a device having relatively moving gripping jaws (see Division E2). An insulating sheet 6 (Fig. 5, not shown) may be slipped over the tying strip to complete the core and to separate it from electrical windings.

Filed: 1925-01-26
Abstract: 228,196. Libbey Glass Co., (Assignees of Kadow, A., Parker, A. C., and Schreiber, C. W.). Jan. 26, 1924, [Convention date]. Blowing.-Relates to a blowing " spindle " of the kind used in the machines described in Specifications 111,122 and 142,765, and consists of a construction to reduce the weight, size, and operating force required by the mechanism for operating the spindle.. Operating mechanism. The machine consists of a number of units supported by a rotating frame, and each unit carries two spindles. The spindles 17, Fig. 1, are carried in bearings 16 on a yoke 15 which is secured to a hub 14 journaled in the frame. The hub has teeth 18 engaging a rack 19 which can be moved transversely by a bell-crank lever 26 oscillated by a cam groove 30 on the central drum 11. The cam governs the oscillation of the spindles about a transverse axis as the machine rotates. Longitudinal rotation of the spindles is effected by means of a bevel gear 45 which is carried by a sleeve. 46 rotatably mounted within the hub 14 and is geared through pinions 42, 43 with teeth 40, Fig. T, formed in the casing 90 of each spindle. A shaft 47 journaled in the hub 14 is slidable through, but drives, the sleeve 46, and is driven by a sleeve 50 mounted in a sliding block 51. The block carries pinions which gear with racks 57, 58 fixed on the drum 11 when the block is forced inwards by a spring 59, but are disengaged when a roller 63 makes contacts with cams fixed to the drum. Thus these cams control the speeds and times of rotation of the sleeve 50 and, therefore, of the longitudinal rotation of the spindles. The relative movements of the different portions of each spindle are produced by the actuation of a bell crank lever 71 mounted on each yoke and engaging a collar 70 formed in the casing 90 of the spindle. The lever 71 is rocked by longitudinal movement of the shaft 47. This movement is produced by a slide 83 which engages a collar 81 on the shaft. The collar is moved radially by a roller 84 which engages a cam groove 85 in a plate 86 secured to the central drum 11. Spindle construction. The outer casing 90 of the spindle has fixed within it an inner casing 92, Fig. 7, on the outer end of which jaws 97, that grip the parison against a receiver 133, are pivoted. These jaws are connected by links to a sleeve 98 which slides on the inner casing 92 and is forced outwards by a spring 104 to close the jaws on the parison. When the outer casing 90 is moved downwards by means of the collar 70, screws 115 encounter the ends of slots 117 in the sleeve 98 and further movement of the casing compresses the spring 104 and opens the jaws. A plunger 147 slides within a socket in the receiver 133 and is held in its retracted position by a spring 150 surrounding its stem. When the casing is moved upwards by the collar 70, the end of the air pipe 132 makes contact with the end of the plunger stem and thrusts the plunger into the receiver. Air is supplied by a flexible pipe 126 to the pipe 132 which does not rotate with the spindle, escape of air being prevented by a packing gland 139.

The double-coned friction member 13 is mounted on the shaft 10, by a sleeve 12 and pins 11 and 14, for slight universal play. The housing is filled with oil through an aperture 17. In operation, the holder is advanced in a drilling machine or capstan lathe against the rotating work. When the tap and work contact, the tap at first rotates with the work but, as the holder is advanced, the cones 6 and 13 engage and hold the tap to cut the thread. When tapping is complete the work rotation is reversed and the holder withdrawn. The oneway clutch 8A then runs free until the cones 7 and 13 engage and hold the tap still. In a modification, the cone 7 is of male form and the co-operating side of the member 13 is female.
